Shelly 2. Gen device script to repeatedly check for WiFi status and reboot the device if disconnected for long enough

shelly_wifi_reconnect.js

// Reboot after 5 minutes of disconnect
let wait_sec = 30;
let retries = 10;

let c = 0;
let timer = Timer.set(wait_sec * 1000, true, function () {
  Shelly.call('WiFi.GetStatus', null, function (result, error_code) {
    if (result.status !== 'got ip') {
      if (c++ < retries) {
        print('wifi not connected, waiting another', (retries - c) * wait_sec, 'seconds until reboot');
      } else {
        print('rebooting to reconnect to wifi');
        Shelly.call('Shelly.reboot', null, function() {});
      }
